To all whom it may concern:

Be it known that I, FREDERICK A. Ronnnas, a subject of the Kin of GreatBritain, residing at Glen Ewen, 1n the Province of Saskatchewan, Canada,have invented certain new and useful Im rovements' in Conibined Harrowsand See ers; and I do hereby declare that the following is'a full,clear,

and exact description of the invention, such as-will enable othersskilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to agriculturalimplements, and particularly to a combined disk harrow and seeder.

Broadly speaking, it comprises a frainework, aplurality of harrow disksarranged in oppositely inclined sections, a set of removable disks, anda 'set of sod cutters and drills adapted to replace the removable disks.

In order to more clearly disclose the construction, arrangement anddisposition of the several parts of the invention, reference should behad to the accom anying drawings forming part of this app icaiton.

Throughout the several figures of the drawings, like referencecharacters designate the same parts.

In the drawin Figure l is a side elevation of the machine, with thedrills attached; Fig. 2 is a plan view of Fig. 1, with the seed box 'indotted lines; Fig. 3 is a central vertical cross section through one ofthe sod cutters, detached; Fig. 4 is a side elevation of Fig. 3; Fig. 5is a front view of the spacing sleeve used with the disks of the sodcutter; Fig. 6 is a vertical section through the means for attaching theharrow disks, one disk being shown in side elevation; Fig. 7 is afragmentary view, showing the connections for rocking shafts 2; and Fig.8 is an enlarged detail View of the connections between the parts 4 and5.

Referring to the drawings in detail, 1 indicates a wheeled frame ofordinary con.-

struction and adapted'to support the. several Working parts of themachine. In this frame are suitably journaled a plurality of paralleltransverse rock shafts 2. to which are secured rock arms 3. To the outerend of each of these arms is pivotally connected :1

a draft beam 6 at a point a short distance from the lower end of thedraft beam. The upper end of each draft beam is journaled to move freelyon a transverse rod 7, while its lower end supports an inclined concaveha r-. row disk 8. In order to enable slight independent movement ofeach disk 8 rclaiively to its connecting rod 4. the connections betweenthe rod and draft beam 6 are made yieldable and comprise a collar 9on.the rod and a coil spring 10 adapted to be inter sed between thecollar and the top 0 the sleeve 5, the opposite endsof the spring beingconnected to the collar 9 and sleeve 5, respectively. I

If it is desired to raise all of the disks of any one section toinoperative position. it is simply necessary to depress the hand levers12. These hand levers 12 are arranged in pairs on either side of thecenter of the machine. so that both levers of any one pair may begrasped and operated at the same time. Each lever is connected by asliding joint to a rock arm 13 fixed to the shaft 2. and is pivoted to arack plate or a notched arc plate 14 fixed to the frame and is providedwith a spring catch adapted to selectively engage the notches of therack plate to hold the disks 8 in adjusted position.

The rear set of disks, instead of being attached directly to the draftbeams 6, are each secured to a plate 15 adapted to be removablyconnected to the draft beam 6. Therefore, it is possible to remove thisrear set of disks and replace them with combination'sod cutters anddrills. This combination attachment comprises pairs of sod cutting disks16, mounted on opposite ends of a sleeve 17, from which extends aconnecting arm or plate 18 and a tubular drill .head 19 adapted toreceive seed from the act to clamp the disks to the ends of the blocks.The disks are provided with flanges 23, adapted to surround the outerends of the sleeves 17 and act to center the disks theredn and reventbending or twisting of the body oft e disk. j

The harrow disks 8 are removably connected to their plates 15 by bolts24 passed through blocks 25 seated in bearings formed in the plates 15.Washers 26 of greater diameter than the ends of theblocks 25 are placedbetween the heads of the bolts 24 and the ends of the bearings, and sohold the blocks 25 and bolts 24 in operative position. The disks 8 areprovided with flanges 27, which act to center the disks and preventbending or twisting of the same. In order to keep dust and grit out ofthe bearing of the disk 8, a dust cap 29 is provided. This dust capisadapted to be screwed over the boss 30, through which the block 25 andbolt 24 are passed.

It is thought that the operation and use of the invention will be clearfrom the preceding detailed descri ti on.

Changes may be ma e in the construction, arrangement and disposition ofthe several parts of the invention, without in any way departing fromthe field and scope of the same, and it is meant to include all suchwithin this application, wherein only preferred forms have beendisclosed.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is

A machine of the characterdescribed comprislng a frame, rockshaftsjournaled therem, a plurality of draft beams pivotally mounted in saidframe, sleeves mounted on said draft beams, rods projectingvinto andslidable in said sleeves, an adjusting collar secured on each of saidrods, a spiral spring sli ped on each of said rods and fastened at itsends to the respective collar and sleeve of said rod, rock arms, in theends of which the upper ends of said rods are pivot-ally secured,connecting said rods to said rock shafts, hand levers arrange in pairspivot-V ing toward or from each other, notched arc plates'to which saidlevers are respectively pivoted, a s ring pressed pin for each leverentering se ectively said notches and rockarms fixedly connected to saidrock shafts and slidably pivotally connected to said leverssubstantially as set forth.

In witness-whereof Ihave hereunto set my hand in the presence of twowitnesses.
